It is our aim to reflect the real usage of all
documents on EconStor by natural persons. Furthermore we intend to provide
usage statistics that are comparable to those from other Online databases
with scientific content, e.g. subject based aggregators and databases from
publishing houses. For that reason we have adopted the internationally
recognized COUNTER codes of practice.

COUNTER
is an international initiative by database hosts (e.g. Thomson ISI, EBSCO,
JSTOR), publishing houses (e.g. Elsevier, Springer, Nature) and
library associations (e.g. Association of Research Libraries) aiming to
establish standards that facilitate the collection, recording and processing
of online usage statistics. Thus, the standards of COUNTER provide for
objective collection and reliable comparability of download figures.
The methods for assessing the EconStor download statistics are in
accordance with the
"COUNTER Code of Practice for e-Resources".
EconStor download statistics according to COUNTER are available since
October 2012. Only PDF-Downloads are measured whereas mere page views
on EconStor are not taken into account.

Additional Filtering of Outliers

Even the standards of COUNTER do not completely
filter all automated accesses on EconStor. Therefore as a rule a download
from one specific IP address is only counted once per day and document.
Beyond that logfiles are checked for outliers in regular terms.
These measures will make sure that our download statistics
correspond best to the real user behavior.
